Derive speed of sound

WebThe experimental value for the velocity of sound in air at NTP was found to be 332 ms -1. This difference between calculated and experimental value shows the need for some correction in Newton's formula. Later on, Laplace made a correction in Newton's formula now known as Laplace's correction. Velocity of Sound in a Gas: Laplace's Correction. WebOct 28, 2024 · The speed of sound in fresh water 1,428 m/s. Water’s elastic bulk modulus is 2.2 × 10 9 Pa. Knowing these two values, we can confirm water’s density. Squaring both sides leaves: or Determining the Speed of Sound The density of cold-rolled steel is 7861 kg/m 3. Its elastic bulk modulus is 159 GPa.

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or one kilometre in 2.91 s or one mile in 4.69 s. It depends strongly on temperature as well as the medium through which a sound wave is propagating. At 0 °C (3… WebDec 19, 2024 · First of all, the speed of sound seems to decrease as the mass of the gas increases. But clearly mass is not the only relevant factor. For example, Argon is heavier than Ethane but sound travels more quickly through Argon. The same is true for Neon and Ammonia.

WebThe speed of sound in solids and liquids can be derived by applying Newton’s laws of motion on a column of the medium of propagation. Generally, the speed of sound in a solid or liquid is the square root of the ratio of the force restoring the particles to their equilibrium position, to the inertia resisting the restoration. ... WebSep 12, 2024 · The speed of the waves on the strings, and the wavelength, determine the frequency of the sound produced. The strings on a guitar have different thickness but may be made of similar material. They have different linear densities, where the linear density is defined as the mass per length, (16.4.1) μ = mass of string length of string = m l.
